Breathing Troubles: Common Causes and Triggers

Interstitial lung disease (ILD) is thought to occur when damage to the lungs triggers an abnormal healing response. This response causes scarring in the tissue surrounding the air sacs (alveoli) and makes it more difficult for oxygen to pass into the bloodstream. Among other complications, 30 to 40 percent of ILD patients also experience pulmonary hypertension as a result of the impeded oxygen flow. ILD can be triggered by long-term exposure to hazardous materials like asbestos or radiation, some types of autoimmune diseases such as rheumatoid arthritis, and in rare cases, as a reaction to medications. Even so, a direct cause is rarely found in most cases of ILD. Similar to long-term smoking and COPD, symptoms for interstitial lung disease include shortness of breath and persistent dry cough. It is important to see your doctor after the first sign of breathing problems, as an early and accurate diagnosis is essential for proper treatment.
